Expand description
Features flags requested for a package.
This should be cheap and fast to clone, it is used in the resolver for various caches.
This is split into enum variants because the resolver needs to handle features coming from different places (command-line and dependency declarations), but those different places have different constraints on which syntax is allowed. This helps ensure that every place dealing with features is properly handling those syntax restrictions.
Variants§
CliFeatures(CliFeatures)
Features requested on the command-line with flags.
DepFeatures
Features specified in a dependency declaration.
